摘要： When an attenuation pole produces, highly-efficient-izing and a miniaturization of a filter are enabled by changing the electric length between a branch point and each filter. The 1st band pass filter 5 that has the characteristics of center frequency f1, and the 2nd band pass filter 7 that has the characteristics of different center frequency f2 from center frequency f1, In co-planer filter 3 provided with transmission line 9 which connects the 1st band pass filter 5 and the 2nd band pass filter 7, and branch point 11 formed in transmission line 9. It is designed so that an attenuation pole may produce in either [at least] the 1st band pass filter 5 or the 2nd band pass filter 7, and the frequency region which the formation position of branch point 11 is adjusted and an attenuation pole produces is adjusted.

摘要： An impedance matching circuit, a semiconductor element and a radio communication device using the same, adjusting bandwidth while permitting it to be constructed on the semiconductor element by reducing its occupation area. Since a reactance compensating distributed constant line (31) compensates reactance (BL, XS) of a load (6) and a quarter-wave transmission line (32) and an impedance inverting distributed constant line (33) composing an impedance inverting circuit (K inverter or J inverter) corresponding to the degree of impedance (ZL, ZS) of the load (6) match the impedance (ZL, ZS) of the compensated load (6) and output the input signals (SI1, SI2) at the preset bandwidth, adjustment of bandwidth can be made while miniaturizing the impedance matching circuit (7a) by shortening the line length of the reactance compensating distributed constant line (31) and the quarter-wave transmission line (32).

摘要： Communication circuit 1 is provided with antenna sections 3, such as a nonresonant antenna, and matching section 5 which connects with antenna section 3 and adjusts impedance, for example.Matching section 5 has a transmission line and the electric length and characteristic impedance of a transmission line are determined based on the frequency or the frequency band in which antenna section 3 and a transmission line resonate.For example, since it is not necessary to unite resonance frequency with center frequency if it is a nonresonant antenna, it becomes possible to attain the miniaturization of an antenna.Wide band-ization is realizable by changing the characteristic impedance of a transmission line.
